REFRlGERATlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 292,925, dated February 5, 1884:.

Application filed October 22, 1883.

(Ne model.)

') all whom ir) may con/&3777,;

State of Texas, have invented a new and useful Improvement in Refrigerating-Machines; and I do hereby declare'the following to be a full, clear, and exact description thereofireference being had to the accompanying drawings, making a part of this specification, in which i 4 Figure 1 is alongitudinal vertical seetiontof my improved refrigerator. Fg. 2 is a plan View of the refrigerator and of the cold-air-distributing box, the covers of the sane being removed. Fig. 3 is an elevation of the fan and infiuent pipes, partly in section; and Fig. 4 is an enlarged View, showing more plainly the construction of the refrigerator-box.

Like letters of reference indicate 'like parts in each. i

My inventio'n relates to the refrigeration of air; and it consists of a box of wood or metal having in it a series of pipes arranged longitudinally in manifold, and extending across it laterally a series oftransverse partitions,which run alternately from opposite sides, said box having a detachable top and hinged sides,`

whereby access may be had to the refrigerating-pipes for repairng and for like purposes. It also consists in the manner of attaching the manifold pipes by means of flanges at both ends to conneeting-pipes, r i It also consists in a perforated cold-air-distributing box placed in the lower part of the room, and a perforated air trunk or box in the upper part of the room, conbined with a suct ion-fan for'withdrawing air from the upper part of the room and forcing it through the refrigeratingbox before mentioned to cool it,

and through the coldair-distributing box into the room.

It also consists of a valve arranged in the V influent opening of the suction-fau, in combi:

nation with a pipe leading from the air-truni; in the top of the room, and with a pipe leading in from the outer air, in such a manner that by shifting the valve the air which is to be refrigerated may be taken either from the room or from the outside.

To enable others skilled in the art to make Construction. i i

The refrigeratng chamber or box is indicated at a. It has a removable top secured to the sides by keys a', and hinged sides, as indicated at a so that the internal Construction may be gotten at for the purpose "of repairs. Inside of this box are two or more series ot' pipes, Z,' arranged longitudinally in vertical series of two or more, as may be desired, and the pipes of each series are attached ,at each end to a connecting-pipe, (l, common to the series, by means of a separate fiange, `d', so that in ease of any accident to the pipe, or in case it is desired to reduce the number of pipes in the chamber, any one or more pipes maybe taken off by simply unscrewing the bolts d and use my invention, I will now describe its and taking off the flange d', without displac i ing or removing other pipes. The openings thus made in the connecting-pipes (Z may be closed by placing a blind or solid fiange over them. i

Arranged at suitable intervals, and extending alternately from opposite sides of the chamber a, are transverse partitions c, through which the pipes I pass. The purpose of the partitions is to cause the air to have a longer run in the refrigerator and to pass over a great-er amount of refrigerating-surfaces The partitions may be arranged as closely as desired or is necessary to produce any required degree of temperature. The same may also `be said with reference to the number of pipes b which are placed in the box. ant is supplied to the pipes b through the pipes 0, connected by fianges o'. This refrigerant may be ammonia or similar gas, or any noncongealable liquid. The air is supplied to the chanber a by means of a sucton-fan, h, operated by a belt and pnlley, k, the air being drawn in at the influent opening i and driven through the pipe ginto and through the chamber a whence it is discharged through the air-trunkl into the distributing-chamber m, whence it passes through the perforations n' into any desired part of the room. The air to be refrigerated may either be drawn from the top of the room by the use of a perforated box or air-trunk e, similar to the air-trunk m, or,

in case it is desired to inject fresh air into the The refriger- IOO -' off through a waste-pipe, a'.

room, through a pipe, p, from the outside. In the influent opening i, I arrange a valve, q, by means of which I an enabled to close the pipe p or the air-trunk leading from the room, so as to draw my supply from either at will. I prefer to distribute the cold air in the lower part of the room' and take the supply from the upperpart, so as to cause the exhaustion of the warm air and a continuous circulation through the room. The moisture from the air is deposited upon the pipes b in the form of frost in the box a. NVhen it colleets so thickly as to interfere with the operation of the re- 'rigerator, it nay be melted out by forcing warm air through the pipes. It is then drawn By this means I prevent the collection of frost in theroom, which, in case of stoppage of the machine, would thaw off and create a dampness.

In case of a stoppage of the machine the room should be closed, and then the air will remain pe'fectly dry and cold for a considerable length'of time.

The advantages of-my machine are sinplieity of Construction, ease of making repairs, ability to make repairs without stopping its operation, ability to obtain any required degree of cold, and the dryness and perfect refrigeration of the air which are obtained thereby.

hat I claim as my invention, and desire to secure by Letters Patent, is-

l. A refrigerating-box having a detachable top and hinged sides, a series of pipes for containing the refrigerant, arranged within said box, and a series of partitions extending alternately from opposite si des near] y across the box, for causing the air to be cooled to make along circuit in passing through the box, substantia'lly as 'and for the purposes de- 40 seribed.

2. A refrigerator box having a series of refrigerant pipes extending longitudinally through it, each pipe being connected at each end with a connecting-pipe by means of sep- 4 5 arate flanges, and the end pipes connected by flanges with supply and discharge pipes, whereby any one or more of the pipes may be taken out or replaced without interfering with the operation of the machine, substantially as and for the purposes described.

3. In combination with a refrigerator, a perforated cold-air-distributing box in the lower part of the room, a perforated air-box in the upper part of the room, and suct-ion-fan for withdrawing the warm air from the room and forcing it through the refrigerator and the coldair box and out into the room, substantially as and for the purposes described.

4. The suction-fan having a Valve, and arranged in connection with a fresh-air pipe, and a pige leading froni the upper part of the room, in conbination with a refrigerator and an air-distributing box, whereby the air may be drawn from the outside or from the room at will, substantially as and for the purposes described.

In testimony whereof I have hereu nto set my hand this 29th day of September, A. D.
